Finding IP addresses on the same wireless internet - HELP.

[OneWayFloww]

Hey guys,


This is my first question I'm throwin' at ya. If you didn't catch my introduction, I'm new here.


How can I find the IP Address of another computer that is using the same wireless internet as me? In fact, he's in the same apartment, I just kinda wanna mess around with him lol

[rucciva]

if you just want to find the ip adress, you can use many tools like wireshark, nmap, hping2 etc,,

for example if you want to use nmap,, u can use this command
$ nmap -sP <your ip address>/24

There are several methods to finding an IP address of a computer on the same LAN.

1. Run a network scan as suggested above, common tools include nmap, angry ip scanner.
2. Check your ARP table from the terminal / command line (arp -a) should be sufficient on both Linux and Windows.
3. Ping the name of his computer (assuming you know it).
4. Login to the web interface of the router and check the DHCP lease table or the NAT table.
5. Go on his computer and run an ipconfig (windows) or an ifconfig (linux) and mark down the IPv4 address.

Hope this helps.

Try netdiscover -i iface

Or you can ping whole subnet by tiping:

windows:

C:\> FOR /L %i in (1,1,255) do @ping -n 1 10.10.10.%i | find "Reply"

linux:

• # ping -b -c 3 255.255.255.255 >/dev/null 2>&1; arp -an | awk '{print $2}'
• $ for i in `seq 1 255`; do ping -c 1 10.10.10.$i | tr \\n ' ' | awk '/1 received/ {print $2}'; done

t13ru, you can ping the whole subnet by pinging the broadcast address of the subnet and checking the ARP table.

If you are on subnet 10.0.0.0/24 for example (10.0.0.0 - 10.0.0.254), you can ping 10.0.0.255 and all of the online computers will respond.
Once you've given it enough time, check your ARP table (arp -a) and you will see all the subnets online devices and mac addresses.


[NOTE] This doesn't work on all networks, I just tested it. So your method is still valid.

I use Net Tools 5, it has a wifi scanner app.

Cain & Able is capable to do this.
First Configure to choose your wifi card, then the + button for ARP scan. and results in a list of active connected devices. (in this example it's my router, not wifi )






When found, you can poison his connection and redirect his traffic
